Is this trial a fit for you?

Probably not a fit

Patients with active suicidal ideation, psychotic symptoms, or those currently receiving other psychological treatments may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This trial investigates the effects of a mobile-based gamified cognitive bias modification (CBM-C) intervention on individuals diagnosed with obsessive-compulsive disorder (OCD). Participants will be randomly assigned to receive either the gamified CBM-C, a standard CBM-C, or a placebo control, with assessments conducted at baseline, after four weeks, and at a three-month follow-up. The study aims to explore how gamification can enhance motivation and participation in cognitive interventions designed to modify cognitive biases associated with OCD. By examining the combined effects of different cognitive bias modifications, the trial seeks to provide insights into effective treatment strategies for OCD.

Why it matters

Potential benefit: If successful, this intervention could significantly reduce OCD symptoms and improve overall psychological well-being for patients.

How similar studies have gone: While there have been promising results from studies on combined cognitive bias modification in subclinical samples, this specific approach using gamification in OCD has not been previously tested.
